How is kinetic energy affected by temperature? the temperature will
the average kinetic
of a system.

Increase in the temperature will increase the average kinetic energy of a system.

From kinetic theory of gases,

K.E. = 3/2KT

where,

As the temperature increases average kinetic energy of system increases. Because when temperature increases the molecular motion increases, due to increase in velocity the kinetic energy of system also increases.

Thanks for joining community.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
